Mark 4 has two parables to consider: Parable of the Sower
and the Parable of the Growing Seed. In
John 10 we have Jesus discourse on The Good Shepherd.
John 10:10
The thief comes to steal, kill and destroy .
What is the enemy trying to steal, kill and destroy?
Answer: The word of God before it produces fruit in our lives. By eliminating the word from entering our heart and mind, Satan can keep us from hearing God’s voice. The parable of the Good Shepherd is about hearing the Good Shepherd voice.
When you compare these three scripture passages everything lines up perfectly.
Bird steals seed.
Sun kills blade.
Thorns destroy kernel head of the ear.
But Jesus came that we may have :
Life which is the seed on the good soil
Life more abundantly : 30, 60 and 100 fold return.
